`IMPROVE,IVIIEFNCI IN WEATHER-STRIPS IlOR DOORS.

Theischedule referred to in the'so Letters Patent and making part of tne name To lIl whom it mag/.concertar y Be it -lniownthat we, Enasfrts G. Corax and ADDISON linten, both otthc otBIaislia-ll, in the county ofOalhoun` and`Sta cot' Michigan, have inrented a "new and [useful` Improvement in Weather- Strps for Doors` `and wedo herebydeclare that thek description 'ot' the an1e,11ef`crence being had to the annexed drawings making a part otthis specification, in which- Figure 1 is a rit-winisometrica] perspective. `Fligurelis a. cross-section through door-sill,

, and

lower pai-tot' door.`

`Similarrletters of retilrenee indicate corresponding Vpartsin both figures.

v Our invention is more especially designed to exclude wind, rain, .or s now from admission into a building through theclcarancespacc' between the lower edge f ot'a door and its sill or threshold, and consists in the peculiarconstruction,` :`arrangcincnt, and combination ot'narts as claimed hereinafter; and, the better to euable others ski-lied in the artgto construct` and apply' our invention, we will now proceed to describe it.

A represents the weather-stri p, laying longitudinally along, the thresholdor sill Bot' a door-way, which strip we usually construct ot' sheetmetal, but it may he of any other materialadapted to the purpose.

We hingicithe outer edgeot'- the weather-strip to vthe sill `in any suitable manner, but generally by brass `wirc staples, (two or inore,) in tho mode substantially as at i, the strip heilig hinged insuch relative posi-v tion withtlie shut door as will presently more t'ully appear, i

As the door 1) sbeing just closed, it impinges against-a short tilting arm, @,he'nt upward at a proper angle, and tilts up the inner side ofthe weather-strip into an angularlreccss or groove, which we form'by cutting and planing away a central strip ot'v the wood vin the bottoniiedge of thedoor throughout its entire width, as may be clearly seen at G.

We secure the tilting-arm c to the. extreme end of' the weather-strip, and -behind the door-stop C, as to he entirely ont otl the way and it willfbe found necessary to out away and recess the doorstop a. little toreceive the thickness of the arm when `said arm is pushed back againstit by the close shutting of the door, and tilting the weather strip into thc door-groove G, as aforesaid.

The extension of strip A behind the stop C has the effect of preventing the entrance of water at this point.

When the door is closed the .weather-strip forms an angle. with the sill, morev or less acute, according to the width ot' the space to be covered ;V the outer edge being hinged, .so as to form a. close joint :with the sill, and the inneredge penetrating the `body ot' the door, all rain or snow that may drift aga-inst.' the door is eftectuaily-shcd and excluded.

Ot' course, when the door is opened, the weather- 'strip A will fall bach on the sill byits own gravity;

but, should itbe deemed necessary to hold it down there withsntticient firmness to prevent accidental,Y

lifting in passing over the. threshold, a. properly graduated spring, as atj, may be screwed to the door-stop; so as to act against the tilting-arm. This spring, it' it have. sutticient` tension, will prevent the door front rattling by the force of the wind; and,` to prevent wearing the door at the point of rubbing contact, a.,

pronged wire or narrow metal strip maybe inserted, as at n.

Our arrangement preserves the external integrity ot the door, is simple. and inexpensive, and, it' property .,erected, seals up the bottom space almost hermetieally against the elements.

We do not cla-im, irrespectively, the lifting a weather-strip by the impingementof the door, in clos-Y ing, against an arm, or any cam-like proiectiomftbr this is not new; but

Having described our` invent-ion,

What we do Lclaim as our invention, and desire to n secure by Letters Patent, is

1. The plate A, when extended behind the stop C, and having the arm e, arranged as shown, said plate being raised bythe closing ot' the door, andfitting into the ,recess G, made as shown, all as'herein .described and represented.

2. In combination with the door-strip, constructed and arranged as described, the springj, as and for the purpose set forth.
